Abstract
1. Autoimmunity in deisease is driven by autoantigen; 2. Cell surface molecules may stimulate autoreactive T-helpers if call II MHC is expressed; special factors may predispose to the ease of class II induction; 3. Soluble autoantigens may be focussed by primed B-cells and processed for presentation to T-cell; 4. autoantigenicity may be influenced by metabolic events: (a) Poorly iodinated thyroglobulin does not induce thyroiditis; (b) IgG rheumatoid arthritis has galactose deficient Fc oligosaccharides. Glycosylation defects may prove to have wide implications.
